BOOT OR SHOE HEEL TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 414,731, dated November12, 1889.

Application filed May 25, 1887. Renewed April 22, 1889. Serial No.308,236. (No model.) Patented in England January 9, 1885, No. 294.

To all 10710111 it 71mg COMO/1771,:

lie it known that I, ROBERT IIEAP SOUTH- ALL, of lleadingley Leeds, inthe county of a patentin Great Britain, No. 294., January 9,

1885;) and I do hereby declare that the following is a full, clear, andexact description thereof.

My invention consists of improvements in machinery for paring the heelsof boots or shoes, and will beclearly understood by the followingdescription thereof, reference being had to the accompanying sheets ofdrawings and the letters of reference marked thereon.

Figure 1 is a side elevation of my machine. Figs. 2, 3, and 4. aredetached views of'different positions of the knife. Figs. 5, 6, and 7are detached views of different positions of the templet. Fig.8 is adetached view of the lever. Figs. 9, 10, and 11. are detached views ofthe grooved screws and attachments. Fig. 12 is a plan view of the platewith central hole. Fig. 13 is a detached view of the slot-ted templet.Figs. 14. and 15 are detached views of the teniplet G with slot.

I construct a frame A for carrying the various arrangements. In a properposit-ion on this frame I secure a fixed pedestal B, on which I place,as on astud, the bevel-wheel O. This is geared into the bevel-wheel D,keyed on the shaft E, which works in hearings in the frame A, and isturned by the winch-handle F.

()n the pedestal B and above the bevelwheel (3, I place the slottedtemplet- G, (shown separately in Fig. 13,) against which works the endof thumb-screw H, the object of the said templet and thumb-screw beingto give proper form to the seat of the boot K and a proper pitch to theheel thereof, as the said teinplet can be moved backward and forward,having a slot L, Fig. 13, by means of the rod M, with screwed end andhand-wheel N working on the screw. This causes the tool 0 and tool frameP to slant in any direction required. I sometimes cast a groove 3 in thetemplet G, like that shown in Figs. 14: and 15. In this case I dispensewith the springs Q, and substitute a roller to work in the groove. Ikeep the tcmplet G in its place by the collar R.

Above the col larand on the pedestal l" ,l place the templet S, (shownseparately on Figs. 5, ti, and 7,) the pedestal being turned down toform a shoulder for it to rest upon. The objectof this templet is togive shape to the top piece of the boot-heel through the roller T,vertical lever U, tool-frame P, and tool 0. I cast, also, with thetemplet S, but above it, the fixed cam V, which I use for giving aproper angle to the knife WV in the tool 0 through the regulation-screwX. (Shown distinctly in Figs. 2, 3, and a.)

By being cast together the templet and fixed cam V can be removed easilyby merely lifting it off the pedestal B when any different size or shapeof heel is required to be pared. The said templet S and cam V are keptsteady by means of the wrought-iron connection-piece y, with a holebored in the end to fit on the pin Z.

I use the steel pin a to facilitate the iixin g of the boot-heel in itsproper position. This pin' (1.,1 place exactly in the center of the topsurface of the tcinplet S, cam V, and wrought-iron connection-piece Y,as shown in Figs. 6 and 7, and I use a metal plate, Fig. 12, with thehole I) bored in the center for the purpose of making a hole in theright place of the leather top piece of the bootheel before it ispaired. By placing that hole on the tapered steel pin the boot-heel iscertain to be fixed in a proper and central position. K is a boot soplaced and held firmly in position by the screw c, working in the boss(1, fixed in the frame A.

On the casting e, bolted to the bevel-wheel C, I hinge the verticallever f on the centers Z, and the said vertical lever,.Fig. 11, I usefor drawing, by means of the springs g, the opposite vertical lever Utoward the center of the pedestal B. To do this and gain sufficientpower, I use the angled lever shown in Fig. 8. The end h, I place in thesocket K and press the handle downward till the pawl Z falls in thenotch on, cut for its reception. I then remove the lever, and the pawlholds the various parts in position till the paring operation iscompleted, when I again. repeat the process of liberating the pawl. Thevertical lever U, I hinge to the casting a at the centers z. The saidcasting is slotted to enable it to be moved either nearer or fartherfrom the center of the pedestal B, and thereby make it suitable eitherfor a tapered or straight boot-heel.

I use the slide 0, which carries the roller T, which works, when inworking position, against the templet S, for the purpose of giving formto the top piece of the boot and draw it backward and forward by meansof the grooved screw 1'), which works in vertical slot q, for thepurpose shown. (See Fig. 9.) By means of the slide 0, I am enabled tomake the boot-heel either larger or smaller at pleasure, for by screwingup the screw the tool is drawn farther from the boot-heel and byunscrewing it is brought nearer. The vertical lever U may therefore beconsidered as a movable platform, which moves round according to theshape of the templet S, against; which it is drawn by the force of thespring g. In this manner I give shape to the top of the bootheel; but asthe seat is of a different form I find it necessary to make the joints0:, in which I work the tool P, so that in reality it becomes a lever,the centers 7" 0" being the fulcrum and the end of the thumb-screw IIbeing one end. The screw II is kept against the templetGby the spring Q,which is drawn tight in the same manner and at the same time as thesprings g. The end of the screw H, working against the templet G, musttherefore give shape to .the top end and to the seat of the boot.

The tool and tool frame or holder are shown in Figs. 2, 3, and 4.

P is the holder or frame for earryingthe tool 0, and works in thecenters 7" in the vertical lever U. Through the lower end passes thethumb-screw II, the end of which works against the templet G. The toolitself works in the centers 25 t. The tool 0, I castin brass or someother suitable metal and of a suit- To this I secure the knife.

able form. The

centers 25 t on which it works I place about a quarter of an inch behindthe cutting-edge, so that whenit begins to cut the leather it has atendency to turn round. In doing so the regulating-screwX comes incontact with fixed cam V, and this keeps the knife atapropercutting-angle. The regulation-screw I place about five-eighthsofaninch in advance of the cutting-edge of the knife, and cause it tosuit largeor small circles by the form I give to the fixed cam V. Toprotect the upper of the boot from being injured by the knife I, Iconstruct the guard to, which I fasten to the lever c, in the properplace of which I secure the stud to, which I place in the bearing boredfor it in the tool-block O.

The spring 00', I use for keeping the guard in its proper place andworking position.

I am aware that various machines for shaping heels of shoes haveheretofore been made. I therefore do not present broad claims for myinvention.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- 1. The combination, in a shoe-heel-shaping machine, ofthe pedestal B, having mounted thereon templets G and-S, cam V, and thepointed steel pin a, substantially as shown and described.

2. The combination, with the pedestal B and its mountings, hereindescribed, of the vertical lever U, fulcrum Z, slide 0, roller T,springs g, vertical lever f, pawl Z, and notch m, substantially as shownand described.

The combination, in the shoe-heel-shaping machineherein described, ofthe tool-frame O, regulating-screw X and guard to, lever V, spring X,and thumb-screw H, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this4th day of May, 1886.
